Low oil pressure light

I had similar issues with my '04 - oil light on at hot idle. I first replaced the oil pump gears (they were cracked) without any improvement. I then replaced the oil sensor. After that, the light did not come on again at hot idle. So I thought I was good. I was using Rotella 15W40 and the Mobil 1 301 filter.
Several weeks later, I just happen to have my oil pan off when someone posted about a "walked" cam bearing and being able to see it from the lower part of the engine. I did that inspection and found that I did indeed have a "walked" bearing.
I decided to tackle the repair myself as the alternatives were expensive. So I tore the engine down to the block, pulled out the cam, and replaced the bearing without removing the engine from the truck. I have never done any mechanical work that extensive before, but with the help of this forum, RAVE, using common sense and taking it slow, I was able to complete the job. I got everything back together and it fired up the first time.
At the same time, I also replaced the head gaskets (they were just starting to go) and the whole cooling system (minus the heater core). That was 10 months ago and the truck is still running really good.
So my point is to not dismiss a walked bearing. Also, it is possible to fix a walked bearing yourself if you decide to take on that challenge.

Yeah, I definitly think I need to formulate a plan of action: there's a few items going on that I'll have to address: there's a slight coolant loss for the last 6 months (about 8oz every 6 to 8 weeks) that we thought was around the throttle body. The oil on the dipstick looks perfect, so if it's the HG, coolant might be burning off. The idle is running a tad high. I'll check the new codes on the SES this week. The car has about 156k, and the HG was replaced before at 100k before I bought it. Although it's my daily driver, I have other cars, so I can take my time doing what needs to be done. Having driven it around today, no problems, other than the idle, and it sounds like I've got hot cams in the engine.
